BACKGROUND The importance of Chlamydia pneumoniae as a cause of pneumonia has remained controversial. The clinical picture of C pneumoniae and Streptococcus pneumoniae in patients admitted to hospital with community-acquired pneumonia was compared during a C pneumoniae epidemic in Finland. METHODS Group I consisted of 24 patients in whom serological testing and bacterial culture indicated an ...

i n a survey of pneumonia due to mycoplasma 282 out of 12168 ovine and caprine lung condemnation were collected (2.32%). mycoplasma spp. has been isolated from pneumonic cases in 4 sheep and 2 goats. pcr studies were confirmed the genus of mycoplasma although attempting for identification of strains m. mycoides, m. capricolum/caprine pleuropneumonia and m. arginin were in failure. the lesions i...

BACKGROUND Pneumonia represents a major health burden. Previous work demonstrated that although the induction of inflammation is important for adequate host defense against pneumonia, an inability to regulate the host's inflammatory response within the lung later during infection can be detrimental. Intracellular signaling pathways commonly rely on activation of kinases, and kinases play an ess...

BACKGROUND A bacterial cause is not frequently identified in children with pneumonia complicated by parapneumonic effusion (ie, complicated pneumonia). OBJECTIVES To determine the frequency of positive blood and pleural fluid cultures in children with complicated pneumonia and to determine whether broad-range 16S rRNA polymerase chain reaction (PCR) improves identification of a microbiologic ...

We present a case of fatal hemorrhagic pneumonia secondary to Stenotrophomonas maltophilia in a patient with acute myeloid leukemia. S. maltophilia is commonly a non-virulent pathogen. However, in the immunocompromised, it is generally associated with bacteremia after central venous catheter placement or pneumonia. Hemorrhagic pneumonia is a rare presentation of this bacteria, with only 31 case...

Until recently, Staphylococcus aureus– associated pulmonary infections have been indistinguishable with respect to the toxin-associated genes in the strains associated with each case. The recent emergence and worldwide spread of community acquired methicillin-resistant S. aureus (CA-MRSA) clones containing the genes encoding Panton-Valentine leuko-cidin (PVL) has led to an increase in the numbe...

background: ventilator-associated pneumonia (vap) is a type of nosocomial pneumonia which develops more than 48 hours after endotracheal intubation. early recognition and treatment of vap is important, since timely and appropriate management can be lifesaving. objectives: this study aimed to determine the antimicrobial susceptibility pattern of microorganisms causing vap in the intensive care u...

objective: in-time diagnosis of streptococcus pneumoniae (s. pneumonia) can play a significant role in decreasing morbidity and mortality rate. applying molecular methods has gained popularity due to the existing limits of routine diagnostic methods. examining the expression of different genes of this bacterium through different molecular methods suggests that lyta gene has a higher sensitivity...

Methicillin-resistant Staphylococcus aureus (MRSA) is the leading cause of bacterial infections in the United States. Severe invasive MRSA infections, which include pneumonia, are difficult to treat because the bacteria are resistant to antibiotics. A new report now shows that immunization against alpha-hemolysin (Hla), a cytolytic toxin secreted by most S. aureus strains, protects mice against...

Mrs S. is an 83-year-old woman with advanced dementia who lives with her daughter. At baseline, Mrs S. is communicative but confused, requires assistance for her activities of daily living, and has little interest in food. Her daughter tries to feed her a puréed diet that she has been following since her discharge from hospital 3 months ago after aspiration pneumonia. Over the past several week...
